A itorneys Patented Sept. a, 1938 UNITED STATES PATENT OFFICE 1 Claim.

This invention appertains to new and useful improvements in battery post connecters, and more particularly to a connecter in the form of a clamp which can be applied and removed from a battery post.

The principal object of the present invention is to provide a battery post clamp of the character described in which a lubricant is contained to prevent corrosion of the battery post with the,

connecter.

Another important object of the invention is to provide a connecter of the character stated which can be readily applied and removed and which can be readily disassembled whenever desired.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a longitudinal sectional view through the connecter.

Figure 2 represents a top plan view of the connecter.

Figure 3-is a horizontal sectional view through the device.

Figure 4 is a side elevational view. Figure 5 is a sectional view on line 5-5 of Figure 3.

Figure 6 is a sectional View on line 6-6 of Figure 2.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents a battery post receiving loop which has a tapered opening therethrough which will permit a cutting engagement of the loop into the battery post.

Numeral 1 represents a cylindrical shaped grease cupwhich has one end portion flattened at 8 for partly receiving the loop 5 and this flat- 4o tened portion 8 is provided with an arcuate cutout portion 9 in its top and bottom sides. The shank In of the loop 5 extends through the cup I and also through the spacer II which is preferably of Bakelite. or some other non-metallic 5 material. The spacer II has a reduced tapered extension lladapted to fit into the enlarged end of the cup 'I and this spacer II has a pocket l3, which with the pocket M in the cup 1 serves to hold a quantitiy of grease or other lubricant 50 which is inserted into the pockets by way of the check valve fitting ii.

The free end portion of the shank I0 is provided with threads IS on which is i'eedable the nut ll. Between the nut II and the spacer II is the 55 washer l8, and obviously by tightening the nut l'l against the washer I 8 and the washer II in turn against the spacer II, the spacer II can be brought into compact relation with the cup I for forming a grease container. Furthermore, in this manner, the shank I0 is fed inwardly and outwardly of this structure so that the battery post (not shown) is clamped between the outer 5 portion of the loop 5 and the arcuate portion 9 of the cup I.

A socket member l9 has a threaded recess for receiving the free end of the shank ill and this has a pocket 20 therein into which the usual bat- 10 tery cable can be sweat soldered or otherwise secured in place.

Obviously, the grease will prevent corrosion of the post with the clamp and the fact that the spacer l I is non-metallic, will prevent cor- 15 rosion between these parts so that these parts can be readily disassembled whenever desired.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, 20 and materials may be resorted to withoutdeparting from the spirit and scope of the invention as claimed hereinafter.

Having thus described the invention, what is claimed as new is: 25

A battery post connecter of the class described comprising a cable attaching and post embracing unit, said unit having loop portion at one end to encircle the battery post, a shank of general rectangular cross sectional form integrated 3o v tubular form at the opposite end, the last named end slidably embracing said rectangular shank portion and coordinating with the loop slidably to permit it to clamp against said post, the complemental portions of said hollow jaw unit surrounding the shank in spaced relation to provide a grease accommodation and retaining chamber, an adjusting and binding nut on the threaded portion of said shank, and a non-metallic spacer member interposed between the nut and said slidable jaw unit, said spacer surrounding the shank in grease-tight contact at one end, the opposite endpcrtion surrounding the shank in spaced relation to communicate with said grease chamber, the last named end 5 portion of the spacer having a reduced extremity fitting in telescopic connection with the adjacent end portion of said jaw unit to provide a substantially grease-tight Joint between the spacer member and said jaw unit.
